Cassava starch as an effective component for Ideal Biodegradable Plastic

Inventions have evolved and continue to evolve such that after several years of study, research and experimentation reach great developments. With continuing efforts to investigate the constituents of Philippine plants, we have pursued investigation of starch of the cassava plant (Manihot esculenta). Cassava tubers were gathered, ground and squeezed to extract starch. Starch obtained was weighed and divided into three equal parts; 80 grams in T1, T2 and T3.

Fish Scales Wastes for the Recovery of Astaxanthin

Fish Scales Wastes from Selected Teleosts-Innovative Sorption Materials for the Recovery of Astaxanthin. This study shows the potential use of fish scales of telleosts chanos and Tilapia nilotica as natural sorption materials in the recovery of astaxanthin. Astaxanthin, a feed additive, is a major carotenoid responsible for the pink-red pigmentation of fish and shrimps.

Aquatic animals cannot synthesize this thus it must be supplemented in their diet. Aside from being a colorant, astaxanthin has both biological and nutritional importance as well as antioxidant property. Astaxanthin therefore needs to be recovered from wastewaters that have been colored with astaxanthin as it may pose serious environmental threats.

GLEAM: Eluding Perceptual Errors in Driving

GLEAM (Glaring Light Emission Auto-Minimizer): Eluding Perceptual Errors in Driving. The rapid evolution of technology shows a rapidly changing world. Cars are among the most common indicators of advancement benefiting the super busy people. However, advancements do not warrant freedom from accidents. Research shows that glare is a common cause of errors in driving. Humans normally adapt to light levels. When a bright light suddenly appears, visibility is affected. This problem with glare is encountered at nighttime when the driver is adapted to lower brightness.

Glare headlight Emission Auto-Minimizer (GLEAM) a modified twelve volts device was mounted in a car to prove if it actually prevents car accidents especially at nighttime. This device is a light sensor which, upon detection of high-intensity light, stops current from flowing to the high-beam and allows current to pass through the low-beam.

Insecticidal Effect of Yellow Oleander Fruit Extract on Rice Bugs

Insecticidal Effect of Yellow Oleander (Thevetia peruviana) Fruit Extract on Rice Bugs (Leptocorisa oratorius). According to the Department of Agriculture Reference Manual (1998), 14% loss of rice is due to rice bugs infestation. A survey conducted in Cuartero, an agricultural town in Capiz revealed that rice bugs rank third among the pests infesting rice. Generally, the study aims to find out if Yellow Oleander fruit extract can be used as insecticide against rice bugs. Specifically, it aims to determine if there is significant difference in the effect of different concentrations of Yellow Oleander fruit extract, and varying the mortality rate (in minutes) on the percent mortality mean of rice bugs.
